1.01.8 Conclusion

Cemented carbides remain a growing market. There has been a continuous expansion in the consumption, from an annual world total of 10 ton in 1930 to about 50,000 ton in 2008. As the world’s economics grow, cemented carbides will play their part in the progress of technology.

New technologies and new materials will demand new tooling solutions, and cemented carbide tools will provide a cost-effective option due to their attractive properties. Modern recycling technologies and a more efficient collection system of scrap material will contribute in this regard, driven by both the price and the need to maintain and save natural resources. In the long term, recycling will inevitably become the key strategic factor for sustained economic growth, and the respective recycling strategies of cemented carbides are in the line.

So, after a period of almost 90 years, cemented carbides have developed from a temporary solution in industry (as a substitute for diamond in wire drawing in the lighting industry) to a very successful and almost irreplaceable material for the manufacturing industry (Schubert et al., 2010).

The authors of this chapter consider it as being very remarkable that from the very beginning of the hard- metals the optimal combination of WC and Co was chosen. Even by 2013, 90 years later, there is no better combination of hard carbide and metallic binder in sight.
